The CyberData SiP-enabled V2 Ceiling Speaker is a Power-over-Ethernet (PoE 802.3af) and Voice-over-IP (VoIP) public address loudspeaker that easily connects into existing local area networks with a single CAT5 cable connection. The speaker is compatible with most SiP-based IP PBX. In a non SiP environment, the speaker is capable of broadcasting audio through multicast.

Configure your switch properly.

LINKSYS SRW224G4P - It is more reliable to use the "Static Member Ports" than relying on the auto discovery of multicast listeners. Just add the "Multicast IP Address" 239.168.3.1, check the port you're plugging in the speaker and press "Add"

In the Multicast Config, Enable Multicast operations by checking the box

Use the default configuration

Save and Reboot

Convert your track using 'sox'

sox mysong.MP3 -r 8000 -c 1 -s -w -t wav mysong.wav
